Sherwood Forest Ashe has the wrong hair color

In Sherwood Forest Ashe's splash art she has blonde hair as you can see here: http://ddragon.leagueoflegends.com/cdn/img/champion/splash/Ashe_2.jpg

But the in game model still uses her natural white hair, as you can see here: https://www.youtube.com/watch?v=F_2uP5BqDAk

Would it be possible to recolor her hair in this skin to have it match the intended color palette?
